...instructors to train their own people in such trades as carpentry, plumbing, home economics, nursing. In the village of Rio Negro in southern Chile, Janet Boegli, 22, from Austin, Texas, shares a small house with two Chilean girls, teaches women how to use a sewing machine, knit, mix powdered milk, clean beer bottles to use for babies' formulas. Chilean volunteers have organized communities of 20-30 houses, called centros. They raise money to buy sewing machines and other needed equipment by organizing fiestas and raffles. "What's important," writes Volunteer Boegli, "is that we have shown that gringos...
Homogenized, pasteurized, refrigerated, U.S. milk is an eminently safe beverage. But U.S. laboratories are hard at work trying to make it even safer. In a cold war world, scientists must somehow learn how to extract the radioactive strontium 90 that is showered down on pasture grass from atmospheric nuclear tests. At present, U.S. cows do not take in enough strontium to make their milk dangerous, but testing may well continue; the problem may well get worse...
...promising solution makes use of ion exchange resins, bits of plasticlike material with metallic atoms built into their molecules. This material can be made to release certain elements in exchange for others. So when milk that has been slightly acidified with citric acid passes through the resin, it loses most of its strontium and picks up a little extra sodium or calcium. A process using this principle was developed by scientists of the U.S. Department of Agriculture, captures 98% of the strontium, but it costs nearly 10? per quart-more than most dairy farmers get for their milk...
...cheaper process developed by Chemistry Professor Harry P. Gregor of Polytechnic Institute of Brooklyn uses thin plastic membranes containing submicroscopic pores that permit the passage of small atoms with positive electric charges. Milk is made to flow along one side of a membrane; on the other side is a solution of such salts as calcium and sodium chlorides that are naturally present in milk. If the milk contains strontium 90 atoms, they pick up positive electric charges from a current flowing through the solution. Then they slip through the membrane and lose themselves in the harmless salts. Dr. Gregor thinks...
...prurience. Prim, black-suited Dr. Antonio (Peppino de Filippo) is a self-constituted one-man vice squad who sees signs of obscenity everywhere. One sign that puts him into a puritanical dither is a huge billboard featuring a slinkily gowned, reclining platinum blonde who holds a mammoth glass of milk in her hand and endorses the consumption of that beverage. "Take her down," says Dr. Antonio to snickering city officials and discreet church fathers. One night, as Dr. Antonio tramps obsessively around the sign, the poster girl (Anita Ekberg) comes down and offers...
